MLM URLs don't work

Question: Today I installed the MLM function on our MaxBulk Mailer. After that, I send our newsletter at 3 e-mail addresses. After receiving the newsletter, every url doesn't work. What can be the problem?

Kind regards.

Answer: Look at the MaxBulk Mailer preferences, second panel. Is the MLM URL correct? It has to start with http:// or https:// and it should work if you try to open it with a browser.

Furthermore, in front of that field you have a menu with several tools to check your MLM install.
